Write license data into meta data of image files

  • Problem: Images files can store license data as meta data inside the file. As of today image files do not provide this data. For nearly all files on Wikimedia Commons license data are available on commons. But they are stored separately on the description page.
  • Who would benefit: Users of Wikimedia Commons files who want to use the file and need the license information but cannot find the corresponding Wikimedia Commons file page.
  • Proposed solution: Write license data from description page into meta data of the image file.

Discussion[edit]

I'm surprised nobody has requested this before. It sounds like a great idea. Is there some reason this has not been done yet? Downtowngal (talk) 00:09, 17 November 2017 (UTC)[reply]

This is not the first time I've heard this proposal. I would like to limit the scope to only the thumbnails. Original files shouldn't be touched. That would have all sorts of nasty side effects (duplicate detection broken to name one). Multichill (talk) 17:10, 17 November 2017 (UTC)[reply]

The common concern about this is file size overhead for small thumbnails. --Tgr (WMF) (talk) 01:05, 20 November 2017 (UTC)[reply]
